Thebase 12 has a substantially flat top surface 20 and a recessed area 30defined by an inwardly extending flange 22. The flange 22 is positionedbelow and recessed with respect to the top surface 20 of the base 12 toform the recessed area 30 below the top surface 20 of the base 12. Aside wall 32 extends between the flange 22 and the top surface 20 of thebase 12 to define the depth of the recessed area 30. The inner edge 24of flange 18 defines the dimensions of the central opening 18. As shownthe flange 22 completely surrounds the central opening 18 to form acontinuous surface. A plurality of screw apertures 26 are formed in theflange 22 for receiving mounting screws to attach the base to the topend of the electrical box 16.

A gasket 28 is provided in the recessed area 30 on the flange 30 to forma seal between the cover 14 and the base 12 when the cover 14 is closed.The gasket 28 is preferably made from a resilient rubber material thatis able form a waterproof or water tight seal between the cover 14 andthe base 12 to prevent water and dirt from entering the box 16. As shownin FIG. 2, the gasket 28 has an outer dimension corresponding to theinner dimension of the recessed area 30 of the base 12 so that thegasket 28 fits within the recessed area 30. The gasket 28 is providedwith a central opening 34 have a dimension corresponding to thedimension of the central opening 18. Preferably the gasket surrounds thecentral opening 18 with a continuous surface to provide the water tightseal between the cover 14 and the base 12. The gasket can be attached tothe top surface of the flange 22 by an adhesive to prevent separation ofthe gasket 28 from the cover assembly 10. The gasket 28 preferably has aplurality of holes 29 overlying the screw holes 26 for accessing themounting screws within the screw holes 26.

The flange 22 of the base 12 has a width to mate with cover 14. Theflange 22 is formed with longitudinal side portions 36, a first endportion 38 and a second end portion 40 opposite the first end portion38. In the embodiment shown in FIG. 2, the flange 22 and side wall 36 ofbase 12 forming the recessed area 30 include a raised member 42proximate the first end portion 38. The raised members 42 in theembodiment shown are provided at each corner of the recessed area 30 atthe first end portion 38. In one embodiment, the gasket 28 has athickness corresponding to the height of the raise member 42 so that thetop flat face 43 of the raised member 42 is substantially flush with thetop surface of the gasket 28. As shown in FIG. 2, the gasket 28 has anotched portion 44 in the two opposite corners to receive the raisedmembers 42. In the embodiment shown in FIG. 2, a raised portion 42 isprovided in two corners of the recessed area at the first end portion 38of the flange 22. Alternatively a raised member can be provided in eachof the four corners of the recessed area 30 as shown in FIG. 1.

The cover 14 is pivotally coupled to the base 12 by a hinge assembly 46.The hinge assembly 46 is configured to enable the cover 14 to pivotbetween a closed position shown in FIG. 3 and an open position shown inFIG. 4. Preferably the hinge assembly 46 allows the cover to pivot openso that the cover 14 lays flat on the top surface 20 of the base 12 andthe surface of the floor in which the cover assembly and electrical boxare mounted. The hinge assembly 46 also enables the cover 14 to pivot tothe closed position shown in FIG. 3 where the cover 14 is seated in therecessed area 30 of the base 12 with the top surface of the cover 14substantially flush with the top surface 20 of the base 12. The hingeassembly 46 provides a full range of pivoting movement of about 180degrees.

The hinge assembly 46 includes a hinge mounting bracket 48 that iscoupled to the first end portion 38 of the flange 22 as shown in theFIG. 2 and FIG. 11. The hinge mounting bracket 48 is attached to theflange 22 by screws 49, rivets or other suitable fasteners. The mountingbracket 48 in the embodiment shown has a body portion 50 with a U-shapedmember 52 at each end for pivotally coupling to a hinge body 54. Asshown in FIG. 11 the body 50 of the hinge mounting bracket 48 is spacedfrom the flange 22 and has a top end substantially flush with the topsurface of the base 12. Each U-shaped member 52 has a bore 56 forreceiving a pivot pin 58. In one preferred embodiment two U-shapedmembers 52 are provided for supporting two hinge bodies 54 forsupporting the cover 14.

Each hinge body 54 is configured for pivotally coupling the cover 14 tothe base 12 and allowing a full range of pivoting motion between thecover 14 and the base 12. The hinge body 54 has a longitudinal dimensionwith a first end 60 and a second end 62. The first end 60 of the hingebody 54 has bore 64 for receiving the pivot pin 58 and pivotallycoupling the hinge body 54 to the bracket 48 and the base 12. The bore64 and pivot pin 58 define a first pivot axis of the hinge body 54 withrespect to the base 12. The hinge body 58 is able to pivot with respectto the bracket 48 and the base 12 between a first position overlying theflange 22 and extending in a direction substantially parallel to theflange 22 with the cover 14 in the closed position as shown in FIG. 5and a position extending in an upward direction substantiallyperpendicular to the flange 22 with the cover 14 in the open position asshown in FIG. 6.

The second end 62 of the hinge body 54 has a bore 66 for receiving apivot pin 68 for pivotally coupling the cover 14 to the hinge body 54.The bore 66 and pin 68 define a second pivot axis of the hinge body 54spaced from the first pivot axis in a longitudinal direction withrespect to the longitudinal dimension of the hinge body 54. In theembodiment shown, the bore 66 lies in a plane that is offset from theplane of the bore 64. In this manner the bores 64 and 66 define twopivot axes that are space apart along the longitudinal dimension of thehinge body 54 and spaced apart in a generally transverse direction ofthe hinge body 54 so that the bore 64 is spaced adjacent a first side 70of the hinge body 54 and the bore 66 is adjacent a second side 72 of thehinge body 54.

As shown in FIG. 2 and FIGS. 5-11, the hinge body 54 has a tab 74extending from the second end 62 in a substantially longitudinaldirection. In the embodiment shown, the tab 74 is aligned with thesecond bore 66 and is offset from a center longitudinal axis of thehinge body 54. The cover 14 has a first end 92 with two slots orrecessed portions 76 for receiving the respective hinge body 54. A hingepin 68 is recessed in groove 81 extending between hinge lugs 83 and iscoupled to the bottom side of the cover 14 by a mounting plate 82 thatis attached to the bottom side of the cover 14 by rivets 84, screws orother fasteners. Bosses 87 extend upward from the inner face of thecover 14 to align the plate during assembly. The hinge pin 68 is alignedwith the recessed portions 78 and extends through the bores 66 of thehinge body 54 to pivotally couple the hinge body 54 to the cover 14.

The hinge body 54 enables the cover 14 to pivot freely between the openposition and the closed position to lay flat against the top surface ofthe base 12 and the floor surface. Referring to FIG. 6, the cover 14seats on the gasket 28 and the hinge body 54 lies against the surface ofthe flange 22 in the closed position. The hinge body 54 preferably has adimension so that the side edge 70 is substantially flush with the topsurface of the cover 14 and the base 12. The cover 14 pivots toward theopen position shown in FIG. 6 about the first pivot axis so that thehinge body 54 pivots upwardly until the hinge body makes contact the topedge of the recessed area 30. The cover 14 continues to pivot to theopen position shown in FIG. 7 about the second pivot axis to lay flat onthe top surface of the base 12 and the floor surface.

To close the cover 14 the cover is pivoted from the position shown inFIG. 7 toward the position shown in FIG. 8. In the first portion of thepivotal movement, the cover 12 pivots about the first pivot axis definedby the pivot pin 58 in the bore 64 at the first end of the hinge body 54until the bottom face of the cover 14 contacts the tab 74 as shown inFIG. 10. The contact of the bottom face of the cover 14 with the tab 74causes the hinge body 54 to continue pivoting simultaneously with thecover 12 to the closed position shown in FIG. 6. The tab 74 limits thepivoting movement between the hinge body 54 and the cover 14 so that thehinge body 54 pivots to the closed position by pivoting about the firstpivot axis of the pin 58. The tab 74 prevents the first end of the cover14 from lifting upward from base when the second end of the cover islatched to the base. As shown in FIG. 6, the tab 74 prevents the hingebody 54 from pivoting about the first pivot axis without pivoting thecover open.

The end of the cover 14 engages the slide surface 43 of the raisedmember 42 during opening and closing of the cover 14 as depicted inFIGS. 9-11. The top slide surface 43 of the raised member 42 forms abearing surface for the edge of the cover 14 as shown in FIG. 8. Theraised members 42 are positioned on opposite corners of the recessedarea forming a bearing or wear resistance surface to contact the edge ofthe cover 14 during the pivoting movement of the cover 14 with respectto the base 12. The raised members 42 prevent the edges of the cover 14from sliding over the surface of the gasket 28 during opening andclosing of the cover 14 to prevent excessive wear to the soft andresilient gasket material.

The cover 14 as shown in FIG. 2 has a shape and dimension to be receivedwithin the recessed area 30 of the base 12. The cover 14 haslongitudinal side edges 90, a first hinge end 92, and a second front end94. A continuous rib 95 extends from the bottom surface of the cover 14to surround the opening in the base 12 and form a seal against thegasket 28. The rib 95 has a height to extend below the top face of theraised members 42 to ensure contact with the gasket 28 and form awatertight seal. As shown in FIGS. 4 and 5, each of the corners at thehinge end of the cover 14 have a recess 97 with a dimension to receivethe top surface of the raised members 42 to enable sealing by the gasketat the corners of the cover 14.

The hinge end 92 has a pair of slots 96 for receiving the hinge body 54.As shown in FIGS. 12-14 the center portion of the hinge end 92 betweenthe slots 96 has an inclined face 98 that slopes from the top facetoward the bottom face of the cover 14. The inclined face 98 forms aflange that engages the body portion 50 forming a cross member of thehinge bracket 48 during the closing moving of the cover 14 with respectto the base 12 and slides over the surface of the cross member. Theinclined face 98 contacts the body portion 50 and slides around andunder the body portion 50 during the closing motion of the cover 14 sothat the inclined face extends under the body portion 50 when the coveris fully closed as shown in FIGS. 13 and 14.

The side edges 90 of the cover 14 each include an access opening 100 anda movable access door 102 to allow electrical cords to pass through whenthe cover 14 is closed. Each access door 102 has an inner edge with agasket 104 and an outer edge 106 for mating with the recessed area 30and the gasket 28 on the base 12. As shown in FIGS. 15-17, the accessdoors 102 each have two hinge pins 108 extending from opposite ends forpivotally coupling with the cover 14. The hinge pins 108 in theembodiment shown have a bent configuration so that the bearing 110 ofthe hinge pins are offset from the base 112 of the hinge pins 108. Thebearings 110 of the hinge pins 108 are received in a complementingrecess 114 in the cover 14 and held in place by a plate member 116. Theresistance to the movement of the doors 102 is provided by an axialcompression member such as a friction washer, rubber O-ring, springwasher or the like. As shown in FIGS. 16 and 17 a compression springwasher 118 is positioned between the recess 114 and the face of thebearing end 110 to provide a frictional force to the access doors 102 toretain the access doors in place while allowing the user to open andclose the access doors as needed. As shown in FIGS. 17 and 18 thecompression spring washer 118 has a generally round perimeter and afirst curved concave face and an opposite convex face that is compressedwhen inserted into the recess 114 to apply an axial compression or forcefrom opposite ends of the access door 102.

The front end 94 of the cover 14 has a sliding latch assembly 120 thatis able to latch the cover 14 in the closed position. The latch assembly120 includes a main latch body 122 that slides within an opening 124 inthe end of the cover so that the body 122 slides between a latchedposition and an unlatched position. A handle 126 is provided foractuating the sliding body 122.

Referring to FIGS. 22-25, the body 122 has a front end 128 with a latchmember 130 having a lower inclined face 132 to assist in closing thecover 14. A corresponding slot is provided in the end wall of the base12 to receive the latch member 130. In the embodiment shown, the sidesof the body 122 have a slot 134 that mate with a corresponding rib 136extending inwardly from the sides of the opening 124 to allow the body122 to slide in a linear direction with respect the plane of the cover14.

Each side of the body has an outwardly extending arm 138 that slides inan open area 140 in the cover 14 adjacent the opening 124. The handle126 as shown in FIGS. 23 and 24 has a substantially U-shapedconfiguration with a pair of legs 146 where each leg has an outwardlyextending pivot pin 142 that is received in a corresponding hole 148 inthe cover 14 to allow pivoting movement of the handle 126 with respectto the cover 14 and the body 122. The legs 146 of the handle 126 have adetent 144 extending in a linear direction and perpendicular to the axisof the pivot pins 142 that engage the arms 138 on each side of the body122. As shown in FIGS. 21-27, the pivoting motion of the handle 126causes the detents 144 to engage the arms 138 to retract the body 122 tothe unlatched position. As shown in FIG. 22 a spring member 150 isincluded between the body 122 and the cover 14 to bias the body 122 tothe closed position.
